Septic System Services in Malibu & Greater Los Angeles

A&B Malibu Plumbing, Heating & Electrical, has serviced septic systems across Malibu and the greater Los Angeles area since 1994. Many homes in canyon and coastal communities rely on septic systems instead of city sewer lines, and these systems need regular care to keep working the way they should. We inspect, repair, and maintain septic systems for homeowners and property managers throughout our service area, backed by CSLB license #722368 and full insurance coverage.

Signs Your Septic System Needs Attention

A septic problem rarely shows up out of nowhere. It usually gives warning signs first. Watch for:

  • Slow drains in sinks, tubs, or toilets
  • A foul smell near your yard or drain field
  • Standing water or soggy patches in the yard
  • Gurgling sounds coming from your pipes
  • Sewage backing up into your home


If you notice any of these signs, call us before the problem gets worse. A small septic issue is much cheaper to fix than a full system failure.

Our Septic Services

We handle every part of septic care, from routine checkups to full system replacement. Our septic services include:

  • Septic tank inspections – We check tank levels, look for leaks, and test the overall health of your system.
  • Septic tank pumping and cleaning – Regular pumping keeps solids from building up and clogging your drain field.
  • Septic repairs – We fix cracked tanks, broken pipes, and failing drain fields.
  • Septic system installation – If your system has failed or your property needs a new one, we design and install septic systems built for your soil and property size.
  • Drain field repair and replacement – A damaged drain field can cause backups and bad odors. We repair or rebuild drain fields so wastewater flows the way it should.

Why Canyon and Coastal Properties Need Specialized Septic Care

Malibu and the surrounding canyon communities have soil and terrain that put extra strain on septic systems. Hillside properties often have limited space for drain fields, and coastal humidity and heavy winter rains can shift soil around a tank or field. Older homes may also have septic systems that were installed decades ago and were never updated to handle current household water use.



Our team has worked on canyon and coastal properties for more than 30 years, so we already know the challenges these systems face. We don't guess. We inspect your system, explain what we find in plain language, and recommend only the work your property needs.

Septic Maintenance Plans

Septic systems last longer when they're checked regularly instead of only when something goes wrong. We offer scheduled maintenance visits that include tank inspections, pumping reminders, and drain field checks. This kind of routine care can help you avoid costly emergency repairs and extend the life of your system by years.
